In the year 290, al-Tabarani quoted `Umayrah b. Sa`d, through Ahmad b. Ibrahim b. `Abd Allah b. Kaysan al-Madini, Isma`il b. `Amr al-Bajali, Mis`ar and Talhah b. al-Musarrif, as saying: I heard ‘Ali imploring, from above the pulpit, the Companions of the Prophet [s] to bear witness if they had heard the Prophet say what he said on the day of Ghadir Khumm. Twelve men stood up - among them were Abu Hurayra, Abu Sa’id and Anas bin Malik- and bore witness that they heard the Messenger of Allah [s] saying ‘To whoever I am his master, ‘Ali is a master. O Allah, befriend the one who befriends him and be at enmity with one who is at enmity with him’.
